Low-reflection coated glass for liquid crystal display and manufacturing method of low-reflection coated glass

Abstract

The invention relates to the technical field of glass panels of electronic display devices, in particular to low-reflection coated glass for a liquid crystal display, which comprises a glass substrate, at least one side of the glass substrate is provided with a functional layer, one side, far away from the glass substrate, of the functional layer is provided with a protective layer, and the protective layer is composed of an antireflection layer, a light absorption layer and a refraction enhancement layer which are stacked in sequence; wherein the antireflection layer is made of silicon dioxide, and nano silicon crystal grains are uniformly distributed in the antireflection layer; the light absorption layer comprises a blue light absorbent, an ultraviolet absorbent and a light stabilizer; the refraction enhancement layer is made of one or two of titanium oxide, antimony-doped tin oxide and tin oxide composite zinc oxide; the invention also provides a preparation method of the low-reflection coated glass for the liquid crystal display. According to the invention, the reflectivity of the coated glass to visible light is obviously reduced, the transmissivity, functionality and practicability of the coated glass are enhanced, and the service life of the coated glass can be prolonged.

Description

technical field [0001] The invention relates to the technical field of glass panels of electronic display devices, in particular to low-reflection glass coated glass for liquid crystal displays and a manufacturing method thereof. Background technique [0002] Float glass is widely used in high-end buildings, high-end glass processing and solar photovoltaic curtain walls, as well as high-end glass furniture, decorative glass, imitation crystal products, lamp glass, precision electronics industry, special buildings, etc. Among them, the liquid crystal display is an active matrix liquid crystal display driven by thin film transistors, and the application of float glass in the liquid crystal display is a common collocation at present. [0003] However, the refractive index of ordinary float glass is 1.52, and its surface reflectivity is about 42%, which not only causes the loss of light energy and affects the presentation of the picture, but also is not conducive to human eye he...

Problems solved by technology

As another example, the patent No. CN103963387A "a high heat absorption and low reflection blue film coated glass and its manufacturing method" uses expensive materials for the structure, the preparation method is complicated, and the coating method is used, which enhances the equipment cost and preparation cost. And its reflectivity is less than 6%, still needs to be further optimized
